A Contribution to the Computer-Aided Analysis of DNA Fingerprint Patterns

Abstract

It is a very urgent task of present forensic identification to exploit the genetic fingerprint for practical work of the Criminal Police. It is necessary to acquire and interprets the features of the DNA-fingerprint with a maximum of objectivity. This urges for the necessity to 1st develop a mathematic model for the criminal evaluation; 2nd create an appropriate system for the image acquisition and image processing; 3rd build up a data base with an efficient search program and 4th open up the possibility of an interactive handling in the image processing and search algorithms in the case of traces. A higher objectivity in comparison to a subjective evaluation is gained by evaluating with mathematical methods the chance which leads to the identifying information. The applied methods of pattern recognition and image processing allow to compare information, influenced by chance and to make a decision as to the identity relatively free of subjective feeling. Thanks to the data bank there exists the possibility to realize an effective search for similar DNA-fingerprint-patterns of traces of unsolved cases or of unknown corpses or missing persons.
